Pff. "Dynamic" typing is "no" typing. I'd much rather say what a variable is up front instead of all this magical hand-waving. In spite of my bitching I still do use Python for some tasks. Things like web scraping and data massaging are way easier in Python than in my bread-and-butter language C++
If it's a fishing trip R has more libraries than Python for things like modeling and machine learning. Python better for NLP. Truth, in a perfect world I would create solutions using both languages. Both languages also offer solutions to be called from other languages so you can add them to your application if you are a C++ or .NET programmer for example.
